Title: Cylinder type silicon epitaxial-layer growth device
Inventor: OTA YUTAKA
IPC: H01L21/205
Filed: 1992-09-28
Abstract: PURPOSE:To prevent generation in a substrate of a crack resulting from sticking to a susceptor after the growth of an epitaxial layer by specifying the spaces and height of projections formed in a bilaterally symmetrical manner to a vertical line passing through the center of a pocket in the lower half of the inner circumferential surface of the pocket. CONSTITUTION:Projection sections 4 are formed on the inner circumferential surface 5 of a pocket, and a silicon single crystal substrate 21 is held into a pocket 2 by abutting the circumferential section of the substrate 21 against the projection sections 4. The height of the projection sections 4 is formed so that the outer circumference of the silicon substrate 21 is separated from the inner circumferential surface 5 of the pocket by at least 0.5mm or more. On the other hand, the projection sections 4 are formed in a bilaterally symmetrical manner to a vertical line L passing through the center of the pocket in the lower half of the inner circumference of the pocket, and the space of the projections is set in 1/20-1/5 of the peripheral length of the silicon substrate. Accordingly, when a silicon epitaxial substrate with a silicon epitaxial layer in thickness of 30mum or more is manufactured, no crack is generated in the substrate at a growth rate of 1.5mum/min.
